Multi-Chassis Fabrics

Introduction

You may use SANbox Switch chassis as building blocks to build a multiple-chassis fabric that will expand the number of user ports beyond the number in any one chassis. Also, the cables used for interconnecting chassis in this multiple-chassis fabric allow you to distribute the network in a campus environment, placing the user ports near to where you need them. The actual cable length is given in Appendix A Reference Information.

.

NOTE:

This description assumes that all chassis are not SL Private Loop stage types. The SL Private Loop stage type allows a reduced version of Cascade topology only. Refer to “SL Private Loop Stage Type” on page 1-5for more information.

There are three major steps in building a multi-chassis fabric:

•Choose a topology.

•Cable the chassis into the selected topology.

•Conﬁgure the chassis and their associated user ports. Conﬁguring the chassis includes assigning stage types and chassis numbers. These topics are described in this section. Conﬁguring the user ports is the same as for a single Switch chassis except you do it on a fabric-wide basis. These topics are covered in the Switch Management manual.

The following paragraphs will lead you through the process of selecting a topology, cabling the chassis, and conﬁguring the chassis into a fabric.
